TO ALL WHOM IT MAY CONCERN:

Be it known that I, S. J'. AUSTIN, of Freeport, in the county of Cumberland, and' State of Maine, have invented a new and improved Baling-Press; and I do` hereby deelsrethat the following' is afull, clear, and exact description thereof, which will enable those shilledfiuthe art to make and use the same, referencebeing had to the accompanying drawings, forming part of this specification, iplwhichfi Figure lis a plan or top view of my invention. p

Similar letters of reference indicate corresponding parts. This invention relates to a new and improved hailing-press, and isan improvement on a press patented by me' 7th February, 1865.. Y i i t The invention consists in'novel means employed for operatin'g-the-platen- 4and Ythe expanding side of the press-box; and also in a peculiar construction of the platenand helad-block,and other features hereinafter fully shown and described, whereby'a very simple, eilcient, and durable press is obtained, and one which may bc operated or manipulated with the greatest facility.

A represents the press-box, which is supported hy a suitable` framing, B. This press-box is provided with 'a movable or sliding side, C, attached to a vertical frame, D, having rollers, arat its upper and lower ends, the lower rollers resting on the bottom of the press-box, and the upper ones bearing against the two upper longitudinal beams b b of the framing B, as shown in tig. 2. The frame D of the side C has four arms, E, attached to it by joints c, two at each side, andthe outer ends of said arms are slotted longitudinally to workon vertical guides d d, attached to the two end uprights e e of the framing D, and said outer ends of the arms have pins, f, passing transversely through them, which pins workA between the guides d d and uprights gg of the framing. The outer ends of the arms E, at cach side of the framing B, are connected by rods L, and the outer end s ofthe upper arms E have cords or chains, F F, attached to them, which pass over pulleys z' z' in the upper part of the framing B, and then extend downward, and are attached to a shaft, G, in the lower part of the framing, said shaft having a pulley, H,upon it. By turning the shaft G in the direction, indicated by'arrow. 1, the outer ends of the arms E will be raised, and the side C of the press-box moved inward in the direction indicated by arrow 2, and by turning the shaft Grin the opposite-direction, as indicated hy arrow 3, .the outer ends of the arms E will he drawn downward, and the side C moved outward, as indicatcdrby arrow 4, (see iig. 2.) I represents a horizontal platen, whichworks up andV down within the press-box Afand underneath a head-block, J, which is fitted in the upperpart of the framing B, the upper surface of said head-block having adove-'tail groove, j, made in it to t on a dove-tail cleat, 7c,in the framing, as shown in iig. 3. By this arrangement the head-block may be readily slipped out and detached-from the framing when necessary. The under side of the lread-bloek'is of concave form, or it may bc described as having pendent lipspl, at its front and rear sides, as shown in fig. 2.`- The upper surface of the platen I is provided with similar lips l', having an upright position, as also shown in fig. 2. To the under side of the platen I the upper nds'of three arms, K K K, are attached by pivots m, the arms K K being attached to the platen n'ear its louter end, and the lever K attached .to said platen near its i'ear end. These arms K K Kar'c ivoted near their centres to arms L, the lower ends of which areconne'cted' byjoints n to the bottom of the framing. These armsK K K and L- form toggles, as will beseen by 4referring to 1fig, 2. To the lower ends ofthe arms K K K there are attached chains or cords, M, which pass underneath the press=box A, and are connected to a'shaft, N. One of thejournnls, o, of this shaft has a screw-thread,p, cut upon it to work in a female screw in its bearings. By this means a longitudinal motion is imparted t0, the shaft N when it is rotated, and the chains or cords M willalways bc kept in line with the arms K K K and L, and not made to pull obliquely upon them, as would be the case were the shaft N allowed to rotate in a fixed position, owingto the ceiling of the chains-or cords around said shaft N. In one side of the pressbox A, at

the rear ofthe head-block J and platen I, there is a door, O, opening inward. To the outer or frontside of the platenI there is attached by joint-s q a. metal apron, P, which, whenA thc platen `I is lowered, covers the slots 'r in Vthe front side of the press-box, in which slots the arms K K K work when the` platen I is raised.

' The operation is as follows: The side C is drawn outwardto its fullest extent in the direction indicated by arrow 4, and the platen I also lowered to itsfullest e.\:tent.4 'lhe hay or other substance to be compressed is thrown into tho-upper end of the press-box A, and the pulley H is turned in the direction indicated by arrow 1, and the side' C moved in the direction indicated by arrow 2, so as to force the substanee to be compressed and baled between the platen I and head-block J. This being accomplished, the shaft Nis thenturned 'and the arms or toggles K K K L are made to raise the platen I, which, when it reaches its culminating point, completes the operation. In consequence of thc arms K K K attached .to the platen fl, as shown and described, the platen is made to ascend in a horizontal position, and by means of the lips ZZ l Z on the head-block and pla-ten, the substance is compressed properly at the angles or corners. When the substance is fully compressed,

.the door O is opened or thrown inward to a horizontal position, and the outer door Q'is thrown open and the hele is then bound or hooped and the bale removed. The side C and platen I nre then moved `back to their original position, the door O closed,- and the operation repented. y

'I do not claim broadly the expanding or sliding side C to :t press-box of n Vberling-prcs's, for that may bc seen in the Iiettersljatent formerly granted to me and previously alluded to; but I do claim :ts-new, and desire to' secure by Letters Pntenti 1. The operating of .the side C through the medium of the arms E, applied at one endto the side C,- and having their opposite ends fitted in or 'between suitable guides with cords or chains F attached, which nrevconnected to a shaft or windlass, G, substantially as shown and described.

2. Providing one of the journals o of the shaft'N with an external screw-thread, phtojvork in en internal screw in 'its bearing, or with an equivalent device, to give the shaft N a longitudinal movement while being.)r rotated, and thereby keep the chins or cords M in line with the arms K K K', substantially as set forth.

Y 3. The lips l'Z l Z', on the level block J and platen I, substantially as and for the purpose herein set forth.

v 4. The securing of the head-block J in the fra-ming' B, by means ofthe d0vetail cleat I: on the framing fitting in the dove-tail groovej in the upper surface of the head-block, substantially as set forth. v

5. The metel opron P, attached to the platenl, substantially as and for the purpose speciiied. y 6. The door O in the side of the press-box A, when used in combination with the sliding or expanding side C and the platen I, arranged substantially as shown and described.
